Application August 3, 1949, Serial No. 108,274 (o1. 229-37) v 2 Claims. I 1

My invention relates to folding cartons, formed from cardboard or like sheet material` and has for its primary object the provision of novel handle means therefor.

A highly important object of my invention is the provision of a novel handle means which may be formed in the blank from which the carton is formed Without the necessity of using any extra material.

Another highly important object of my invention is the provision of a novel handle means which makes possible the use of relatively lightweight and inexpensive cardboard or other sheet material.

A still further object of my invention is the provision of novel handle means for folding cartons, which lie within the plane of the carton top When not lin use, but which may readily be opened to operative position with a minimum of time and effort.

The above and still further important objects and advantages of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.

Referring to the drawings, wherein like characters indicate like parts throughout the several views:

Fig. 1 is a plan view of a blank embodying my invention in generally flat position; l

Fig. 2 is a view in perspective of a partially closed carton formed from the blank of Fig. l;

Fig. 3 is a perspective View of the carton of Fig. 2 in totally closed position;

Fig. 4 is a perspective view of my novel carton showing the handle elements moved to their operative position; and

Fig. 5 is a transverse section, taken substantially on the line 5--5 of Fig. 4.

My novel carton is made from a single blank I of sheet material, preferably light-weight cardboard or the like. The blank I is generally rectangular in form and is scored to provide longitudinally-extended fold lines 2 and transverse fold lines 3. The front lines 2 and 3 define opposed side Walls 4 and 5, end Walls 6, a glue flap l, and top and bottom closures. The bottom closures include end flaps `8 integrally formed with the end walls S and side ilaps 9 integrally formed with the side walls 4 and 5. The top closure includes end flaps I0 integrally formed with the end walls 6 and side flaps II integrally formed with the side walls 4 and 5.

As shown, the closure flaps II are partially severed in generally U-shaped designto provide handle-forming blanks, as indicated at I2. It

will be noted that the extreme ends of the slit r2 terminate adjacent, but in spaced relation, to the inner edge portions I4'. The closure flaps II are scored to provide foldlines I5 that extend between` opposite ends of the slit I2 tofacilitate opening of the-blanks I3 with respect to the closure flaps I I toward theirl hand-forming positions. It will be noted that the slits I2 at their intermediate portions are bridged by the material forming the closure flaps II, as indicated at I6, whereby the blanks I3 are normally retained in the plane of the flaps II. Segmental notches I'I in the closure flaps II adjacent the slits I2y permit insertion of fingertips or the like for breaking the bridging portions IB when it is desired to move the blank I3 into handle-forming position. A yplurality of longitudinally-spaced finger-receiving openings extend through the blanks I3 and preferably, and as shown, intersect the fold lines I5 atspaced intervals. End closure flaps I 0 are provided with angular slotted openings I9 which are spaced from each other and extend from the intermediate portions of said flaps laterally outwardly to a point indicated by the numeral 20,from whence they extend toward the inner end 2 I, terminating closely adjacent thereto as indicated at 22.. As shown, the slots I9 are' preferably of the general shape of the opposite ends of the slits I2, but, in any event, underlie the opposite end portions of slits I2 when folded to the position indicated in Figs. 2 and 3. It will be noted that thev closure flaps I0 underlie the closure-flaps I I and are rigidly and securely adhered thereto by a suitable glue or adhesive. The end flaps II] are scored to provide fold lines 23 that extend from the inner end of each sl'ot I9 to the ends 2| of the flaps Ill. The scored fold lines 23 underlie portions of the fold lines I5 when the blank I is folded to provide a closed carton. As indicated in Figs. 2, 3 and 4, segmental notches 24 in the inner ends of end aps Ill register with finger-receiving openings in the opposite end portions of the blank I3.l

In forming the complete carton from the blank I, a suitable adhesive is applied to the glue flap I and to the end closure flaps 8. The carton is folded along the transverse fold lines A3 and the flap I adhered to the inner side of the free end portion of the side wall 4. The bottom closure flaps and 9, are folded inwardly with the side flaps 9 underlying the end flaps 8, said flaps then being adhered together to providek the bottom closure.

The carton is adapted particularly for carrying goods in cans, such as canned beverages, fruit juices and the like. Such cansk are shown by dotted lines in Figs. 3 and 5 and indicated by the character When the carton is filled with the cans as, the endflaps I are folded inwardly and the upper surfaces thereof coated With a suitable adhesive. The side flaps II are then folded inwardly and adhered to the end flaps I0 to provide the top closure.

The handle-forming blanks I3, normally vlying within the plane of the top closure flaps II, provide arelatively at upper surface tov the carton. This arrangement enables thevlled cartons to be easily stacked to an appreciable, height for storage, shipment and display. f

From the above, it should be obvious that when the cartons of Figs. 2 to 5, inclusive, are formed from the blank Land the closure iiaps II adhered to the closure flaps I0 as at Fig. 3, moving of the handle-forming blanks I3 toward each other, as indicated in Figs. 4 and 5, Will cause the portions of the flaps I0 underlying the blanks to move therewith. This movement, of course, severs the-bridging portions I 8A and the end portions of the naps I0 adjacent the vends 22 of the slots I9. Thus it Will be seen that the handles formed from the blanks I3 are of double thickness` at their opposite ends (see particularly Figs. 4

and Y K v i While 1 have shown a commercial embodiment of my device, it will be understood that the same ,-is capable of modification Without departure from the scope and spirit ofthe invention as defined inthe claims.

W/hat I claim is:

'1. A carton made vfromablan'k sheet of material, said blank includingV side and end wall sections and top and bottom closures, said top closure including a pair of end flaps and a pair of side fiaps, one of which pairs overlies the other oi" said pairs in opposed relationship, each of said overlying flaps being partially'severed in generally U-shaped design to provide co-operating handle-forming blanks which are adapted to open toward each other, the underlying pair of said ilaps being provided with generally L- shaped slots which follow the line of severance of the'opposite ends of the overlying handleforming blanks and terminate in close proximity Ato the inner edges of said underlying flaps, fold lines intermediate the free ends of the line of severance defining the handle-forming blanks, and a plurality of alignable finger-receiving apertures in each of said blanks, a portion of each of said apertures intersecting said fold lines, said pairs of top` closure forming aps being rigidly adhered together, whereby when the handleforming blanks .are opened a portion of each of the underlying flaps will adhere to and reinforce the opposite end portions of said blanks.

2. The structure defined in claim 1 in which the opposed overlying aps terminate closely adjacent each other whereas the opposed underlying 'flaps are spaced a considerable distance from each other `whereby to underlie and reinforce only the. opposite end portions `of said handle-forming blanks.
